[Serusers] serweb: "sorry -- cannot open write fifo"

Hello, I have installed ser 8.14 with serweb that comes with it. Ser works smothly, I can apply aliases too, but the problem is when I open the web interface the page opens fine, but there is a red line saying: serweb: "sorry -- cannot open write fifo" I changed the rules of ser_fifo file in /tmp to 777, didn't help. And both ser and serweb look for the same fifo file, I can see that in config files. How can I get rid of this problem, becouse this way serweb doesn't do instant messages or many other things. I also added fifo_mode=0666 to my ser.cfg file and restarted, nothing changed Thanks in advance Ertugrul
